This invention relates to paper making machines; and it comprises aslice assembly in which an exceptionally wide range of adjustment isobtained by mounting the slice plate so that it may be raised or loweredwith reference to th web forming element or swung to different angularpositions about an axis that is shiftable to different positions alongthe path of travel of the web forming element.

According to the preferred embodiment of this invention the ends of theslice plate are fitted 16,1938, Serial No. 248,785

in guideways afforded by a pair of swivel plates.

ed through end members of the supporting beam and are arranged withtheir lower ends resting on suitable portions of the swivel plates. Acharacteristic feature of this assembly is that the lip of the sliceplate, in addition to being raised and lowered with reference to thesheet forming ele--' ment maybe shifted to different positions along thepath of travel of said element by (a) swingmg the slice plate about itshorizontal axis or (b) shifting said axis in a horizontal plane alongsaid path of travel. Means are also provided for effecting localadjustment of the slice lip at different points along its length.

Proceeding now to a more detailed description reference will be had tothe accompanying drawings, wherein- Fig. l is a front elevation of theslice assembly applied to a Fourdrinier paper making machine.

As shown in these drawings th ends of slice plate 5 are slidably fittedin guideways or grooves 6 formed in the opposing surfaces of a pair ofswivel plates 1. Plate 5 is also provided with guide strips 8 working insupplementary guideways 9 afforded by suitably recessed cleats Illattached to the swivel plates 7.

porting beam ll. This beam is shown as a hollowmetal tube equipped withseparately formed terminal extensions l3. Adjusting screws M arethreaded through vertical openings provided in the extensions i3 so thatthe lower ends of the screws rest on supports I5 carried by the swivelplates 1. The screws Mare provided with reduced ends I? which are seatedin recesses i5a formed in the supports 15. Each swivel plate 1 (Figures4 and fills provided with diametrically opposed arcuate slots I9 for thepassage of bolts 20 which serve to releasably clamp the swivel The slotsis of each plate I are curved about a centre coinciding with the axis ofa centrally located socket 22 formed in the outer surface of said plate.This socket receives a trunnion 23 which, in conjunction with thetrunnion 23 journaled in companion plate I, affords a horizontal axisabout which the swivel plate i may be turned to swing the slice plate 5to different angular positions as indicated by the full and dotted linesin Fig. 10. The trunnions 23 are formed by the reduced inner ends ofsuitable clamping bolts 24 which serve to releasably clamp the slides 2!to the frame members it. As here shown, each bolt passes through anelongated horizontal slot 25 formed in the frame members it and isprovided with an inner threaded portion 26 engaging in a threadedopening 21 provided in one of the slides 28. Washers 28 are interposedbetween the outer sides of the frame members It and the heads 29 of thebolts 2d. Obviously, when the bolts 2 are tightened against the washers28 the slides M are drawn against the inner sides of the frame membersI6 and held against movement relative thereto. The slots 25 formed inthe frame members I6 permit the slides 2i and the bolts 2 lto .beadjusted in a horizontal plane when said bolts bers l6 and project intoelongated horizontal- Figs- 10 and 1 are diagrams showing the diigrooves3| formed in the outer sides of the slides.

The upper edge of plate 5 is welded to a sup- It will thus be seen that,by adjusting the slides 2! in a horizontal direction, the horizontalaxis about which the slice plate 5 is swingable may be shifted in eitherdirection to diflerent points along the path of travel of theFourdrinier wire 32. This adjustment of the slice plate is indicateddiagrammatically in Fig. 11 by dotted lines X and X. In addition to thepreviously mentioned adjustments, the slice plate 8, as indicated bydotted lines X in Fig. 11, may be raised and lowered in the guideways tand I by appropriate adjustment of the height regulating screws I. Thesescrews, after being turned to give the desired adjustment, may be lockedin place by suitable lock nuts Ila.

The slice plate 5 is provided with the usual flexible lip Ia. This lipis fastened by brackets 38 to the lower ends of a plurality of adjustingscrews 3| which constitute the means for effecting local adjustment ofthe lip at diil'erent points along its length. The upper portions of thescrews 34 pass through. brackets 35 projecting from supporting beam Iiand are equipped with adjusting nuts 30.

In some instances it is desirable to have the lip of the slice platepositioned just beyond the delivery end of the rubber apron cloth 38over which the stock flows onto the forming wire 32. In such cases thecomponent parts of the slice assembly are arranged as illustrated byfull lines in Figs. and 11. With the parts in this posi tion, the slicelip 5a may be raised to the dotted.

line position K (Fig. 11) or to any other elevation by appropriateadjustment of the raising and lowering screws N. If it is desired toswing the lip of the slice plate from the full line position to eitherof the dotted line positions shown in Fig. 10, this is accomplished byloosening the nuts and turning the swivel plates I in the properdirection about the axis afforded by the trunnions 23. For any angularposition of the slice plate I with reference to the forming wire 3!, thepivotal axis of the plate may be shifted longitudinally of the formingwire 32 by loosening the nut 24 and moving the slides. Ii in thelengthwise direction of the slots 25. This gives the plate adjustmentrepresented by dotted lines X and X (Fig.11).

Having thus described my invention, what I claim is:

1. A paper making machine including a travelling carrier on which thepulp stock is deposited to form a sheet, frame members projectingupwardly above the carrier at opposite sides of said machine, a pair ofplates slidably secured to the'inner sides of said frame members forsliding movement in'a horizontal direction of the frame members, a pairof swivel plates mounted for turning movement about horizontalsupporting pivots carried by and movable with said first mentionedplates, a slice plate extending between said swivel plates and havingits end portions slidably fitted in grooves formed in the opposingsurfaces of said swivel plates, a vertically adjustable beam mounted onsaid swivel plates, said slice plate being secured to and supported bysaid beam.

2. A Fourdrinier paper making machine including a forming wire, framemembers extending above the forming wire at opposite sides thereof, aslide plate slidably secured to the inner side of each frame member by asupporting bolt secured to the slide plate and working in a horizontalslot provided in the frame member, dowels extending inwardly from eachframe member into a horizontal groove provided in the outer surface ofeach slide plate, a swivel plate carried by each slide plate at theinner side thereof, a slice plate supporting beam extending between saidswivel plates and supported thereby for adjustment toward and away fromthe underlying surface of the forming wire, and a slice plate dependingfrom and supported by said slice plate supporting beam, the ends of theslice plate being slidably fitted in grooves provided in said swivelplates.

3. A paper machine as set forth in claim 2 including means for securingthe swivel plates in various adjusted positions with reference to theslide plates.

4. A Fourdrinier paper making machine including a forming wire, framemembers projecting above the forming wire at opposite sides thereof,each frame member being provided with a horizontally extending slot andwith a pair of dowels projecting inwardly therefrom, a slide platearranged against the inner side of each frame member over the slottherein, said slide plate being provided with a horizontal groove in itsouter surface to accommodate the dowels which extend clamping boltshaving threaded formed in the opposing surfaces of said swivel plates.
